PLEASE EXPLAIN
A steel plate 5/16 in. thick is embedded in a horizontal concrete slab and is used to anchor a high-strength vertical cable as shown in the figure below. The diameter of the hole in the plate is 0.75-inches, the ultimate strength of the steel used is 36 ksi, and the ultimate bonding stress between the steel plate and concrete is 300 psi. The designers considered a factor of safety of 3.60 is desired when P = 2.5 kips. Address the following: (a) Identify three potential failure modes for the complete system. For each mode develop a sketch which idealizes the mode of failure. (b) If you where required choose dimensions for the plate ("a" and "b"), how would you size these dimensions? (c) For one of the failure modes identified above, perform an analysis to determine adequate plate dimensions ("a" and "b") to support the required load of 2.5 kips with the established factor of safety. in.

4. The stepped circular bar shown below is made from aluminum (E = 70 GPa, v = 0.35). Each segment is 400 mm in length. Prior to applying the loads, the bar has the dimensions shown. The structure is axially loaded as shown. Determine the stress in each segment, the maximum stress and its location, the final in length of the structure, and the final diameters of each segment due to the applied loads. All dimensions shown are in mm. Ø 25 40 15 ↑ Fu 300 kN 600 kN 300 kN
The figure shows a flat hanger bar for supporting shop equipment in a factory. The bar is fixed to a support by means of a bolted connection. The main part of the hanging bar is 1.5 inches wide. This width varies up to 3.0 inches. A 1.0-inch diameter bolt transfers the hanger bar load to the two top bracket plates. Determine the allowable stress of the tension load P in the hanger in the following two instances: to. The allowable tensile stress in the main part of the hanger is 16,000 psi. b. The allowable stress load between the hanger bar and the bolt is 26,000 lb/pu.
Question #4 Bar (1) in the figure has a cross-sectional area of 0.75 in². If the normal stress in bar (1) must be limited to 30 ksi, determine the maximum load P (in kips) that may be supported by the system. The connections at A, B and C are pins. A 6 ft D B (1) 4 ft
The rigid bar BCE is supported by two links AB and CD as shown in Figure 1. The Link AB is made of aluminum (E = 70 GPa) and the link CD is made of steel (E = 200 GPa). Both links have a Width= 35 mm x thickness= 7 mm rectangular cross-section. Each of the four pins A, B, C and D has a 5 mm diameter. For the 30 kN force at point E,
